GASKET OB WASHER CUTTER.

Specification of Letters Patent.

Patented Dec. 24, 1907'.

Application filed larch 25,1907. Serial No. 364.852.

To all whom it may concern:

Be it known that I, ELIAS J. PATTON, a citizen of the United States, residin at Hastings, in the county of Adams on State of Nebraska, have invented a new and useful Gasket-Cutter or Washer-Cutter, of which the following is a specification.

This invention relates to machines for cutting washers or gaskets and has for its object to provide a strong, durable and comparativel simple machine of this character in whio the cuttin tool is mounted for rotation over the an ace of the work and adjustable laterally of the cutter bar thereby to permit the formation of washers or gaskets of different thicknesses. A further object of the invention is to provide means for centering the work on the supporting table, and means for feeding the cutter automatically to the work.

A still further ob'ect of the invention is to generally im rove t 's class of machines so as to increase t eir utility, durability and efficiency.

Further obiects and advantages will apgear in the fol owing description, it being unerstood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the ap nded claims.

11 the accompanying drawings forming a part of this specification: Fi e 1 is a side elevation of a washer or gas at cutting machine constructed in accordance with m .invention. Fig. 2 is a top plan view 0 the same.

Similar numerals of reference indicate corresponding parts in all of the figures of the drawings.

The improved machine forming the subject matter of the present invention includes a supporting base or table 5 preferably circular in form, as shown, and having one end thereof reduced to form a neck or extension 6 on which is mounted a spacing block 7 carrying an over-hanging arm or bracket 8.

One end of the bracket or arm 8 is secured to the table 5 by bolts or similar fastening devices 9 while the opposite end thereof is provided with a vertically disposed opening in which is seated a bearing sleeve or collar 10.

Mounted for rotation in the sleeve or collar 10 is a vertically1 disposed o crating shaft 11 one end of whic is rovide with a terminal crank handle 12 whi o the opposite end there of is formed with a vertically dis )osed recess or hearing 13 for the reception 0 a centering pin 14.

The in 14 extends through the bottom of the table or support 5 and is provided with a terminal point adapted to pierce the leather, rubber, fabric or other material of which the washers are formed, said in also forming a journal for the lower end of the operating shaft 11.

The lower end of the operating shaft 11 is provided with a transverse recess in which is mounted for longitudinal movement a horizontally disposed cutter bar 15 having one face thereof graduated in inches and fractions thereof so as to permit the cutting tool 16 to be adjusted longitudinally of the bar thereby to permit the formation of washers or gaskets of different thicknesses.

The cutting tool 16 is mounted for vertical movement in a slot or recess in the adjacent end of the bar 15 and disposed adjacent said cutting tool and mounted for rotation on a sleeve or collar 17 is a wheel or roller 18 ada ted to bear against the work 19 and hold the latter in engagement with the upper face of the table during the cutting or severin operation.

xtending vertically from one end of the cutter bar 15 is a rod or bolt 20 the upper or free end of which is threaded for engagement with a nut 21, the latter being provided with a plurality of radiating arms or fingers 22 which extend in the path of movement of a pin 23 carried by the over-hanging arm 8 and serve to automatically feed the cutter to the work in the manner hereinafter explained.

Interposed between the cutter bar 15 and the nut 21 is a coiled s ring 24 one end of which is assed throng 1 an openin in the upper en of-the cutting tool 16 a! serves to normall and yieldably support the tool in elevate position.

The stop pin 23 is adapted to engage any one of a series of openings 25 formed in the over-han ing arm 8 so that when the cutter bar is ad usted transversely of the o crating shaft 11 to permit the formation 0 gaskets or washers of different thicknesses the pin ma he removed from one of the openin s an placed in an adjacent o )ening so as to )e in position to actuate the leading device or nut 21 when the ()])0I[Ltlll '8lil1ft :is rotated.

The openings 25 are pre erably dis metal in staggered relation, as best shown in l h of th? drawings while the pin 23 is formed in an en arged head or finger piece 26 by means of p'hipih the pin may be convenient y manipuate In operation the rubber, leather or other material is placed in position on the supporting table and centered with respect to the o erating shaft 11 by means of the pin 14.

e cutter bar 15 is then adjusted longitudinally and the stop pin placed in the pro )er ogpning in the over-banging arm 8 a ter w ich the shaft is actuated by rotating the handle 12 thus revolving the cutter bar and causin the cutter to engage the upper surface of the work. As the cutter bar 15 revolves the fingers 22 on the feeding device or nut 21 will intermittently enga'e the adjacent end of the stop in 23 an thus automatically rotate the ceding device or nut against the tension of the coiled spring 24, thereby exerting a downward ressure on the cutter 16 and automatically f eding the latter to the work, the wheel or roller 18 serving to revent accidental displacement of the wor during the cuttin operation. As soon as one incision or cut we been made in the material the cutter bar is adjusted longitudinally the desired distance and the 0 eration repeated thus forming the was er. After the washer has been formed the surplus material may be removed from the table or if desired a smaller washer may be formed from the surplus material in the manner before described.

In order to remove the surplus material from the supporting table it is merely necessary to exert an upward pull on the operating handle 12 which causes the shaft 11 to move lon itudinally within the sleeve 10 and thus e evate the recessed end of the shaft 11 out of engagement with the pin so that the material may be readily detached from the latter and a new piece placed in positon on said table.

From the foregoing description it is thought that the construction and operation of the device will be readily understood by those skilled in the art and further description thereof is deemed unnecessary.

Having thus described the invention what is claimed is:

1. A machine of the class described including a work sup )orting table, an overhanging arm SQCHIOL to the table and provided with a plurality of spaced openings, an operating shaft journaled in the free end of the arm, a cutter bar extending transversely through the operating shaft, a cutting tool secured to one end of the bar, a threaded rod carried by the cutter bar, a nut engaging the threaded end of the rod and provided with spaced radiating fingers, a spring interposed between the nut and cutter bar and operatively connected with the cutter, and a pin projecting through one of the openings in the over-hanging arm and adapted to engage the fingers on the nut for feeding the cutter to the work when the shaft is rotated.

2. A machine of the class described including a work supporting table having an over-hanging arm secured to one end thereof, a sleeve carried b the free end of the arm, an operatiiw shat journaled in the sleeve and provided with a terminal socket, a work eenterim pin secured to the table and engaging tlie socket, a cutter bar mounted for rotation with the shaft, a cutting tool slidabl mounted for vertical movement on one cm of the cutter bar, a threaded rod carried by the cutter bar, a nut engaging the threads on the rod and provided with spaced radiating fingers, a spring interposed between the nut and cutter bar and operatively connected with the cutter, and a stop pin dependin from the over-hanging arm and adapter to en age the fingers on the nut for automatically ecdin the cutter to the work.

In testimony that I claim the foregoing as my own, I have hereto ailixed my signature in the presence of two witnesses.
